The order was given after testing found E.coli and coliform bacteria in the town's water supply. The boil-water order applied to the entire Wellesley water system, and will likely be in place through the weekend.

"While we believe at this time that the potential health risk is relatively small, we take any contamination threat seriously," a statement from the town said.

Residents were advised to boil water for at least one minute before using it or to use bottled water.

Babson College, which is located in Wellesley, advised its students and staff to use bottled water.

Wellesley has a population of approximately 28,000 residents and many businesses and restaurants.
